In Mastercam, CAM Assist starts each operation it creates from your Mastercam operation defaults. To get peck drilling, or any other default it doesn't set itself, change the operation defaults in Mastercam before you run CAM Assist.
What CAM Assist takes from your defaults
When you send the program to Mastercam, CAM Assist creates each operation from the operation defaults for that toolpath type, then sets the values it's responsible for. Your defaults are kept for everything else.
CAM Assist sets these itself, so your defaults for them are replaced:
- The tool
- Feeds and speeds
- Depths, tip compensation and breakthrough
- Clearance, retract and feed planes
These come from your operation defaults:
- The drill cycle for drills, for example Peck Drill
- Peck amounts and other cycle settings
- Any other setting CAM Assist doesn't change
Two hole-making tools always get a fixed cycle, whatever your defaults say:
- Taps use the tap cycle.
- Reamers use the simple drill cycle.
Set peck drilling as the default
- In the Toolpaths Manager, open the Machine Group's properties.
- In the Machine section, expand Libraries and click Edit operation defaults.
- Select the drilling toolpath and click its Parameters row.
- In Cut Parameters, change the cycle to Peck Drill.
- Set the peck amounts and any other cycle settings you want.
- Click the green check mark to save.
The new defaults apply the next time you run CAM Assist and send the program to Mastercam. Operations CAM Assist already created don't change.
